Lu Changsheng felt a burst of excitement.
Even the Spiritual Fires that drifted between heaven and earth could be rewarded by the Disciple Apprenticeship Simulator.
Lu Changsheng obtained a seventeenth-grade Spiritual Fire, which also had other uses.
Lu Qinglian possessed a special magical artifact called the "Nirvana Flames Red Lotus".
The Nirvana Flames Red Lotus could grow by devouring various kinds of Spiritual Fires.
Currently, the Nirvana Flames Red Lotus was a superior Holy Artifact with twenty-four lotus petals, far from its limit.
Lu Changsheng then summoned Lu Qinglian, instructed her to bring out the Nirvana Flames Red Lotus, and first fed it with the seventeenth-grade Spiritual Fire "Void Black Flame".
The Void Black Flame was densely covered in eerie black runes, resembling a black hole and exuding a terrifying swallowing force.
For even an Immortal Emperor, such a high-level Spiritual Fire posed a threat.
